MPEG Audio Decoder (MAD) is a GPL library for decoding files that have been encoded with an MPEG audio codec.^[2] It was written by Robert Leslie and produced by Underbit Technologies. It was developed as a new implementation, on the ISO/IEC standards.^[3]

It consists of libmad, a software library, and madplay, a command-line program for MP3 playback. libmad is notable for using only fixed-point arithmetic^[3]^[4]^[5] while madplay is notable for its ReplayGain support.

Development ended decades ago, and vulnerabilities identified since then have gone unpatched.^[6]^[7]^[8]
